Hortensia, taken in from an orphanage by a ducal family, became a duke's daughter.

However, she failed to assimilate with her family and was bullied by the servants, enduring painful days.

Eventually, she moved to the royal court as a candidate for the prince's fiancée, but was accused of the attempted assassination of another candidate.

"You are a disgrace to the ducal family. I have never once considered you my sister."

Forsaken by her only family, her step-brother, she was swiftly executed for a false charge.

But when she next awoke, time had rewound to the day she was taken in by the ducal family!

This time, she absolutely wants to lead a peaceful life...!

To ensure her survival, she tried her best to win the favor of her step-brother, only to find that...

"What's wrong, Sia? Why are you crying? Who made you sad? Tell me, and I'll eliminate them."

Yet somehow, she finds herself loved with an overwhelming, overprotective affection – this was completely beyond her expectations!
